ABSTRACT:
A mass spectrometer includes an ion source and at least one vacuum stage, a means for delivering ions from the ion source to the vacuum stage, a collision cell, a detector, at least two multipole ion guide segments, and independent RF frequency and DC voltage sources applied to the multipole ion guide segments, the RF frequency and DC voltage sources being controlled independently of each other.
